Lateral Isotopic Discontinuity in the Lower Crust: An Example from Antarctica
Explore this paper's citation graph
Summary
The isotopic differences in the lower crust across the boundary suggest that the current faulting and rifting may coincide with an older crustal suture, the age of which is uncertain.
